Abstract

Using scanning tunneling spectroscopy (STS) at 4.2 K, we observed impurity resonance in single crystals of Zn doped Bi2Sr1.6La0.4CuO6+δ (T C =28 K) (Bi2201). Many impurity resonances characterized by the peak structure near E F were observed. We found that the number of the resonances was less than that of the doped impurities (0.45 % determined by inductively coupled plasma optical emission spectrometry). The resonance peaks were observed only in the region having smaller gap less than Δcut∼26 meV. This Δcut was about half of that reported in Bi2Sr2CaCu2O8+δ .
